To provide a temporarily fastening tool of a fastener placeable in a seat part of an installation hole, and capable of automatically temporarily fastening, while making its axis coincide with the center of the installation hole, by holding the fastener.
Since first to third rotary bodies 14, 29 and 35 for rotating by sandwiching a flare nut 53 in respective tip parts 2a and 3a and a motor 7 for supplying rotational driving force to these first to third rotary bodies 14, 29 and 35 are arranged in the temporarily fastening tool 1 for temporarily fastening to the installation hole by sandwiching the flare nut 53 by opening and closing the tip parts 2a and 3a separating in a bifurcated shape, when a worker sandwiches the flare nut 53 by the tip parts 2a and 3a of the temporarily fastening tool 1, the first to third rotary bodies 14, 29 and 35 rotate in the same direction by driving of the motor 7, and the flare nut 53 is rotated, and when the worker places this flare nut 53 so that the axis coincides with the seat part of the installation hole, the flare nut 53 is automatically temporarily fastened to the installation hole.
